* Name: setup_temporary_directory
* Description: create a temporary directory from specified components
* and return full path to the directory created
* Arguments: r_dirname - pointer to handle to string - on success,
* the full path to the temporary directory created
* is returned in this handle
* a_tmpdir - pointer to string representing the directory into
* which the new temporary directory should be created
* a_suffix - pointer to string representing the 5-character
* suffix to be used as the first part of the temporary
* directory name invented
* Returns: boolean_t
* == B_TRUE - temporary directory created, path returned
* == B_FALSE - failed to create temporary directory
* 'errno' is set to the failure reason
* NOTE: Any path returned is placed in new storage for the
* calling function. The caller must use 'free' to dispose
* of the storage once the path is no longer needed.
